Estimation of Wave Directional Spectra from PitchRoll Buoy Data

Estimates of the directional wave spectrum are generally extracted from data obtained by a heavepitchroll buoy. Many different spectra estimators are now available, and there is a question as to which one is the more reliable in different environmental conditions. Routine data analysis and wavespectra calculation require a computationally efficient and robust estimator. Five different directional spectrum estimates are compared for both …
